Android-ndk soundtouch lib

Hi, I am working on a project, in which I want to build kind of music composer with changing of pitch,tempo and play-rate in real time. From last few days I am working on it and searched enough. I found native Library SoundTouch which is perfect for me what I need. What I am looking here is: -Have great Knowledge and experience to work with Android-ndk and JNI. -Comfortable working with Soundtouch Library and Please have a look on this page([login to view URL]). - You No NEED any designing in this project just put 5-6 simple buttons and do the coding on those buttons(as I just need those back-end codes mainly and I will do designing myself). And yes that's all. I will provide paper designed stuff and all what steps and instructions You will need to complete this task. As i said earlier if you are familiar with Android-ndk and JNI, then this project won't take you to complete more than 1-2 days. Thanks for considering.
